Richie Finally Gets It:'I Have a Responsibility'

8/1/2007 8:17 PM PDT BY TMZ STAFF

In tomorrow's interview with Diane Sawyer on "Good Morning America," Nicole Richie is going to sound very strange -- like an adult!

Richie, who has (finally) admitted to being four months pregnant, handled Sawyer's questions like a champ. When asked about putting people's lives at risk with her DUI arrest last December, Richie said, "If I could personally apologize to every single person that has lost a loved one from drunk driving, I would." Not bad, Nicole. Not bad at all.
